VIP/Confidential/Private Tickets

It would be helpful if we could have a checkbox or something that would allow us to mark certain tickets as VIP/Confidential/Private to further limit access to them in the ticket system. There could be a similar checkbox in the user account that would allow us to designate which users are allowed to see tickets marked that way. An example of when this would be helpful is when a ticket is created for an employee that is leaving or being terminated, but there are other sensitive topics where this functionality could be useful as well.
